论文摘要
我们采用了分形式弹性二元性，在二维的玻色粒超氟中发展了零温度涡流晶体的低能量有效理论，该理论自然结合了晶体拓扑缺陷。我们在这些缺陷之间提取静态相互作用，并研究由涡流空位/间隙和位错的希格斯缩合触发的几种连续量子转变。我们提出，涡流晶体朝着近似或近晶相的量子熔化可能通过一对被中间涡流超固体相分离的连续过渡发生。
Employing the fracton-elastic duality, we develop a low-energy effective theory of a zero-temperature vortex crystal in a two-dimensional bosonic superfluid which naturally incorporates crystalline topological defects. We extract static interactions between these defects and investigate several continuous quantum transitions triggered by the Higgs condensation of vortex vacancies/interstitials and dislocations. We propose that the quantum melting of the vortex crystal towards the hexatic or smectic phase may occur via a pair of continuous transitions separated by an intermediate vortex supersolid phase.
